“…Further experimental progress is anticipated thanks to new and planned facilities. At CERN, the second experimental area at n TOF (Weiss et al 2015) has a shorter flight path to deliver higher neutron fluxes, while the FRANZ (Alzubaidi et al 2016) facility at the University of Frankfurt (Germany) and SARAF (Mardor & GuberBerkovits 2013) at the Soreq research centre (Israel), should soon deliver significantly higher fluxes, and thus sensitivity and precision.…”

The main s-process taking place in low mass stars produces about half of the elements heavier than iron. It is therefore very important to determine the importance and impact of nuclear physics uncertainties on this process. We have performed extensive nuclear reaction network calculations using individual and temperature-dependent uncertainties for reactions involving elements heavier than iron, within a Monte Carlo framework. Using this technique, we determined the uncertainty in the main s-process abundance predictions due to nuclear uncertainties link to weak interactions and neutron captures on elements heavier than iron. We also identified the key nuclear reactions dominating these uncertainties. We found that β-decay rate uncertainties affect only a few nuclides near s-process branchings, whereas most of the uncertainty in the final abundances is caused by uncertainties in neutron capture rates, either directly producing or destroying the nuclide of interest. Combined total nuclear uncertainties due to reactions on heavy elements are in general small (less than 50%). Three key reactions, nevertheless, stand out because they significantly affect the uncertainties of a large number of nuclides. These are 56 Fe(n,γ), 64 Ni(n,γ), and 138 Ba(n,γ). We discuss the prospect of reducing uncertainties in the key reactions identified in this study with future experiments.

“…In addition to the direct use of the neutrons, we are planning to use them within a twostage target to produce exotic light ions at extremely high rates. The first stage is liquid lithium, and the second, which is irradiated by the neutron flux, is selected based on the specific exotic light ion that one seeks [5,6,7].…”

“…In SARAF, we will explore the precision frontier by generating ultra-pure samples of exotic nuclei and trapping them. We will produce light exotic nuclei such as 6 He, 8 Li and Ne isotopes in unprecedented amounts [10], trap them, and measure their b-decay parameters with ultra-high precision [11]. These decay parameters (angular correlations, polarization asymmetry, life-time, transition energy and more) may provide signatures for beyond-SM phenomena, including scalar and tensor transitions, time-reversal violation, right handed currents and neutrinos, and deviation from CKM quark mixing matrix unitarity [9].…”

“…2). The first SARAF measurements in this context will be of b-n correlations of 6 He and Ne isotopes, in search of tensor and scalar components of the b-decay. For 6 He we will use an Electrostatic Ion Beam Trap (EIBT) and for Ne a Magneto-Optical Trap (MOT) (Fig.…”

“…By use of a novel liquid lithium jet target (LiLiT) [1,2], we generated up to 5×10 10 epi-thermal neutrons/sec, mainly for nuclear astrophysics research of slow neutron capture processes (s-process) [3] and also for feasibility studies of Boron Neutron Capture Therapy (BNCT) [4]. For an overview of SARAF Phase I and its ongoing and near future plans, see [5,6] and references therein.…”

The Soreq Applied Research Accelerator Facility (SARAF) is under construction at the Soreq Nuclear Research Center, Yavne, Israel. When completed at the beginning of the next decade, SARAF will be a user facility based on a 40 MeV, 5 mA CW proton/deuteron superconducting linear accelerator. Phase I of SARAF (4 MeV, 2 mA CW protons, 5 MeV 1 mA pulsed deuterons) is already in operation. By use of a novel liquid lithium jet target (LiLiT), we generated up to 5×10 10 epithermal neutrons/sec, mainly for nuclear astrophysics research of slow neutron capture processes (s-process). We present a survey of research programs and plans at the completed SARAF, which span several disciplines: Precision studies of beyond-Standard-Model effects by trapping light exotic isotopes, such as 6 He, 8 Li and Ne isotopes, in unprecedented amounts (including meaningful studies already at Phase I); extended nuclear astrophysics research with higher energy neutrons, including generation and studies of exotic neutron-rich isotopes relevant to the rapid (r-) process; high energy neutrons cross section measurements for basic nuclear physics and material science research, including neutron induced radiation damage; neutron based imaging and therapy; and novel radio-pharmaceuticals development and production.
